Problems solved by technology

The mobile station cannot arbitrarily determine the transmission data rate of the reverse link channel
This is due to the fact that certain mobile stations using high data rates can cause severe interference to other mobile stations, making the system unstable

Embodiment Construction

[0032] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0033] figure 1 is a view of a flowchart of a method of determining a reverse data rate according to a preferred embodiment of the present invention.

[0034] refer to figure 1 , the mobile station receives data rate control information (RCB) and retransmission control information (ACK / NACK) transmitted from the base station (S10). The retransmission control information is information transmitted from the base station to the mobile station, and indicates whether to retransmit the service data according to whether there is an error in the service data (transmitted from the mobile station and received by the base station). If retransmission is unnecessary, an ACK signal is transmitted. And, if a retransm...

Abstract

A method for determining a data rate for transmitting traffic data from a mobile station to a base station in a mobile communication system includes steps of receiving data rate control information from at least one base station; obtaining, based on the received data rate control information, a maximum transmittable data rate; obtaining a plurality of data rates for transmitting traffic data to the at least one base station, the plurality of data rates being obtained by considering a status factor of the mobile station; and determining the data rate of the traffic data to the at least one base station by selecting one of the obtained maximum transmittable data rate and plurality of data rates. The method determines the reverse data rate based on data rate control information and according to its own status, to provide system stability and minimize interference with other mobile stations while increasing the throughput for the sector and maintaining a desired QoS level even when the mobile station transmits at less power while.

Description

[0001] This application claims the benefit of Korean Application No. P2003-29967 filed on May 12, 2003 and Korean Application No. P2003-29966 filed on May 12, 2003, which are hereby incorporated by reference in their entirety. technical field [0002] The present invention relates to a mobile communication system, and more particularly to a method of determining a data rate in the case of transmitting traffic data from a mobile station to a base station in the mobile communication system. Background technique [0003] Much work has been done to develop a framework for the Supplemental Channel (SCH) as the traffic channel proposed by IS2000 (Release D Reverse Link). The mobile station cannot arbitrarily determine the transmission data rate of the reverse link channel. This is because a particular mobile station using a high data rate can cause severe interference to other mobile stations, making the system unstable. To solve this problem, the base station adjusts the reverse...
